Comparing JSF, Spring MVC, Stripes, Struts 2, Tapestry and Wicket

Introductions Your experience with webapps? Your experience with Java EE? What do you want to get from this session? Experience with Maven, Tomcat, Hibernate, Spring? Web Framework Experience: Spring MVC, Struts 2, Stripes, JSF, Tapestry, Wicket © 2007 Raible Designs, Inc.

Who is Matt Raible? Power user of Java Open Source Frameworks Author of Spring Live and Pro JSP 2.0 Founder of AppFuse and AppFuse Light Member of Java EE 5, JSF 1.2 and Bean Validation Expert Groups Committer on Apache Projects: Roller and Struts Java Blogger since 2002 © 2007 Raible Designs, Inc.

JSF Pros: Java EE Standard - lots of demand and jobs Fast and easy to develop with initially Lots of component libraries Cons: Tag soup for JSPs Doesn't play well with REST or Security No single source for implementation © 2007 Raible Designs, Inc.

Spring MVC Pros: Lifecyle for overriding binding, validation, etc. Integrates with many view options seamlessly: JSP/JSTL, Tiles, Velocity, FreeMarker, Excel, PDF Inversion of Control makes it easy to test Cons: Conﬁguration intensive - lots of XML Almost too ﬂexible - no common parent Controller No built-in Ajax support © 2007 Raible Designs, Inc.

Stripes Pros: No XML - Convention over Conﬁguration Good documentation (easy to learn) Enthusiastic community Cons: Small Community Not as actively developed as other projects Hard-coded URLs in ActionBeans © 2007 Raible Designs, Inc.

Struts 2 Pros: Simple architecture - easy to extend Tag Library is easy to customize with FreeMarker or Velocity Controller-based or page-based navigation Cons: Documentation is poorly organized No feedback for missing properties or invalid OGNL expressions Googling results in Struts 1.x documentation © 2007 Raible Designs, Inc.

Tapestry Pros: Very productive once you learn it Templates are HTML - great for designers Lots of innovation between releases Cons: Documentation very conceptual, rather than pragmatic Steep learning curve Long release cycles - major upgrades every year © 2007 Raible Designs, Inc.

Wicket Pros: Great for Java developers, not web developers Tight binding between pages and views Active community - support from the creators Cons: HTML templates live next to Java code Need to have a good grasp of OO The Wicket Way - everything done in Java © 2007 Raible Designs, Inc.

Evaluation Criteria Ajax Support: Is it built-in and easy to use? Bookmark-ability: Can users bookmark pages and return to them easily? Validation: How easy is it to use and does it support client-side (JavaScript) validation? Testability: How easy is it to test Controllers out of container? © 2007 Raible Designs, Inc.

Evaluation Criteria, cont. Post and Redirect: How does the framework handle the duplicate post problem? Internationalization: How is i18n supported and how easy is it to get messages in Controllers? Page Decoration: What sort of page decoration/ composition mechanisms does the framework support? Community and Support: Can you get questions answered quickly (and respectfully)? © 2007 Raible Designs, Inc.

Evaluation Criteria, cont. Tools: Is there good tool (particularly IDE) support for the framework? Marketability of Skills: If you learn the framework, will it help you get a job? Job Count: What is the demand for framework skills on dice.com and indeed.com? © 2007 Raible Designs, Inc.

Ajax Support Is Ajax support built-in and easy to use? JSF: No Ajax support, use ICEfaces and Ajax4JSF Stripes: No libraries, supports streaming results Struts 2: Dojo built-in, plugins for GWT, JSON Spring MVC: No libraries, use DWR & Spring MVC Extras Tapestry: Dojo built-in in 4.1 Wicket: Dojo and Script.aculo.us (Wicket Stuff) © 2007 Raible Designs, Inc.

Bookmarking and URLs JSF does a POST for everything - URLs not even considered Stripes uses conventions, but you can override Struts 2 has namespaces - makes it easy Spring MVC allows full URL control Tapestry still has somewhat ugly URLs Wicket allows pages/URLs to be mounted © 2007 Raible Designs, Inc.

Validation JSF has ugly default messages, but easiest to conﬁgure Spring MVC allows you to use Commons Validator - a mature solution Struts 2 uses OGNL for powerful expressions - client-side only works when specifying rules on Actions Tapestry has very robust validation - good messages without need to customize Stripes and Wicket do validation in Java - no client- side © 2007 Raible Designs, Inc.

Testability Spring and Struts 2 allow easy testing with mocks (e.g. EasyMock, jMock, Spring Mocks) Tapestry appears difﬁcult to test because page classes are abstract, Creator class simpliﬁes JSF page classes can be easily tested and actually look a lot like Struts 2 actions Wicket has WicketTester, a powerful solution Stripes has Servlet API Mocks and MockRoundtrip © 2007 Raible Designs, Inc.

Post and Redirect The duplicate-post problem: redirect after POST Is there support for allowing success messages to live through a redirect? Spring MVC allows you to add parameters to a redirect Stripes, Tapestry and Wicket all have quot;ﬂashquot; support Struts 2 requires a custom solution JSF requires a custom solution, i18n messages difﬁcult to get in page beans © 2007 Raible Designs, Inc.

Internationalization JSTL’s <fmt:message> tag makes it easy No standard for getting i18n messages in controller classes Stripes, Spring MVC and JSF use a single ResourceBundle per locale Struts 2, Tapestry and Wicket advocate separate ﬁles for each page/action JSF requires resource bundle to be declared on each page Tapestry's <span key=quot;key.namequot;> is awesome © 2007 Raible Designs, Inc.

Page Decoration Tiles Experience: used since it ﬁrst came out SiteMesh is much easier to setup and use Tiles can be used in Struts 2, Spring and JSF Requires conﬁguration for each page SiteMesh can be used with all frameworks Requires very little maintenance after setup SiteMesh not supported or recommended for use with JSF, Tapestry or Wicket © 2007 Raible Designs, Inc.

Marketability of Skills Struts 1 is still in high-demand and widely-used Spring is getting more press, but mostly due to the framework’s other features JSF is becoming popular; awful with JSP Struts 2 is gaining ground, but very scarce on job boards Tapestry has increased in popularity in last couple years Wicket and Stripes are virtually unknown © 2007 Raible Designs, Inc.

Mailing List Traffic Struts Stripes MyFaces Tapestry Wicket 0 500 1,000 1,500 2,000 * Spring MVC is not listed here because they have a forum instead of a mailing list and I couldn’t ﬁgure out a way to count the number of messages for each month. © 2007 Raible Designs, Inc.

6 Important Factors What type of Application are you building? Ease of Development / Is full-stack an option? Project Community Project Future and Roadmap Maintenance Technical Features © 2007 Raible Designs, Inc.

Don’t believe the Hype Don’t believe blogs and articles Try it yourself Believe developers, not evangelists Believe developers that are experienced with the framework and have used it in production Beware of corporate interests - they can twist marketing Books are a good sign © 2007 Raible Designs, Inc.

Best Tool for the Job Frameworks have sweet spots - is your application one of them? Pick 2-3 frameworks for your type of application... ... and prototype! If prototyping is painful, switch Make sure you prototype more than one and do a presentation comparing the pros and cons of each © 2007 Raible Designs, Inc.

After Choosing... Document the reasons for your decision Allow developers to challenge it Allow your prototype to be written with other frameworks Don’t be afraid to try new frameworks Don’t be afraid to use old frameworks Don’t be afraid to keep your existing framework © 2007 Raible Designs, Inc.

Conclusion The future is bright because of all the competition Developers should know more than one web framework You should try a framework before dissing it The plethora of web frameworks is a good thing! Doing proper research can save time and money Testing is the best path to future maintenance © 2007 Raible Designs, Inc.
